Spam Header Routine not working

[Raphael Schneider]

Hello,

i am trying to integrate rspamd with UCS Server with Kopano.

UCS uses X-Spam-Flag headers to deliver spam to spamfolder.

So I was trying to rewrite the spam header from X-Spam to X-Spam-Flag, but with no success.

My local milter_headers.conf looks like this:

use = ["spam-header","x-spamd-result","x-rspamd-queue-id"]

routines {

   spam-header {

     header = "X-Spam-Flag";

     value = "Yes";

   }

}

In the headers there is still X-Spam = Yes, but I think this is coming from x-spamd-result and my own spam-header routine is ignored.

There are also no errors in the log about a wrong configuration.

What am i doing wrong?

Thank you very much for a reply.

Greeting

Raphael
